- •
Improvement of the area-averaged local relative velocity in gas-dispersed flow.

Covariance in area-averaging total, group-1, and group-2 void fraction are addressed.
- •
Boiling and adiabatic condensing/flashing flows are considered.
- •
Easily implemented correlations are proposed for important void fraction covariances.
